一、前言地开石是一种比较少见的粘土矿物,是含水的层状铝硅酸盐。它与高岭石相同,属于1:1型高岭石族二八面体。但层的堆叠方式不同,各层的位移是1/6a_0 1/2b_0。在扫描电镜下地开石晶体一般比高岭石厚大,堆叠成塔形,即呈假六方板状晶体,一端较小, First, the preface Dickite is a relatively rare clay minerals, is a water-containing layered aluminosilicate. It is the same as kaolinite, belonging to the 1: 1 kaolinite family of octahedrons. However, the layers are stacked differently, and the displacement of each layer is 1 / 6a_0 1 / 2b_0. In the scanning electron microscope to open the stone crystals generally thicker than the kaolinite, stacked into a tower, that was false hexagonal plate-shaped crystals, one end of the smaller,
